While the aza-di-π-methane rearrangement is the normal photoreactive behaviour of β,γ-unsaturated imines and oxime acetates, the results obtained in this study show that 1,3-migrations of acetoxyimino groups in β,γ-unsaturatedoxime acetates takes place only when all the parameters are correct. The rearrangement takes place when there is a quaternary carbon separating the two π-systems and when one
